Lights are a bit confusing there. Coming from Birkenhead you have a green filter arrow for a left turn but straight on is still red.
Confusion is that the physical straight on (ie the A533) is signed as a left turn (but there is also a true left turn) and the physical right turn is signed as straight on.
Likewise in the opposite direction, physical straight on (A533) is signed as right turn, physical left is signed straight on.
Coming down from Tollemache Road and turning right is also highly unusual, you suddenly end up in what feels like no-mans-land.
I'd challenge anyone that is not familiar with the layout to feel comfortable in all those manoeuvres. Those of us that used it regularly when it was a roundabout still have a counter-intuitive feeling.
